NTTED STATES PATENT EETCE JOHN JAY ANDERSON, OF MEXlOO, MEXICO.

oAR-AxLl-z Box.

SPECIFICATION forming part of Letters Patent No. 414,746, dated November 12, 1889.

Application filed July 13, 1889. Serial No. 317,498. (No model.)

To all whom it may concern:

Beit known that I, JOHN JAY ANDERSON, a citizen of the United States, now residing in the city of Mexico, Republic of Mexico, have invented new and useful Improvements in Car-Axle Boxes, of which the following is a specilication.

My invention relates to an improvement in axle-boxes which are provided with yokes and end stops or buffers in that portion of the axle-box known as the yoke, which holds down the lid of the box, and also in that portion known as the end stop or buffer on the inner side of the lid, against which the axle end plays; and the objects of my improvements are respectively to prevent the yoke from being gradually forced upward out of place, thus allowing the lid or cover to swing open and admit dust, and, secondly, to affordl an easy method of renewing the friction-surface of the end stop lwhen worn out without replacing the whole cover. which I attain these objects are illustrated in the accompanying drawings, in which- Figurel is a side elevation of myimproved axle-box, showing the lid closed, with the yoke and catch in position; Fig. 2, a vertical longitudinal section of the same; Fig. 3, an end view of the removable end piece or wearplate, enlarged; and Fig. 4, a top plan View of a portion of the buffer, showing the method of attaching the wear-plate. l

Similar letters refer to similar parts throughout the several views.

In the drawings, A represents the caraxle, and B the axle-box. The box :is preferably rectangular in cross-section, and is provided with an enlarged axle-opening h in one end d. The end CZ is provided with a vertical groove or socket f, opening at the bottom, and in which a dust-guard Dl is fitted to slide loosely, said guard being provided with a circular opening for the axle, around which it closely fits. The car-axle A revolves within the axle-box B, which is supported thereon by an ordinary bushing X, secured in the top thereof, the space S below said axle being filled with lubricating-packing. The end of the box is closed by the lid L, which is hinged at Q to the outer end of the box. This lid is held down in place by a yoke Y,

hinged at P to the sides of the box. A butter The means by E projects inwardly from the lid L near its to p, said buffer being provided centrally with a longitudin ally-arranged horizontal socket g. A wear-plate R is provided willi an arm M, adapiedto enter the socket in said buifer, in which it is secured by a detachable pin K, passing transversely through the buffer and plate-arm. The lid'L is provided at its lower edge with a lip or thumb-piece h, and at each vertical edge with an outwardly-projecting iiange 1', the outer edges j of said iianges being curvedvertically. A lug k, formed at the lower end of each curved edge of said flanges, supports the yoke Y when the lid is closed and locked. Hinged centrally at m to the outer end of the yoke there is a T-shaped catch O, the outer face p of which is curved, said catch being of sufficient length to engage the lid L when closed.

In boxes of this class as ordinarily constructed the buffer is quickly worn away by the friction of the axle. To replace it, it becomes necessary to substitute a new lid C, said buffers being made integral therewith.

Moreover, the constant blows and jarring of the axle against the buffer frequently causes the yoke Y to work upward and release said lid. In my improvement these objections are overcome. By constructing the buffer to receive a detachable wear-plate, as described, which may be easily removed and substituted by a new one as rapidly as worn, a great saving is' effected. The catch O falls of its own weight inwardly between the lid-flanges 2', and its headv p engages the face thereof, securely locking it and preventing the yoke from being thrown upward by the action of the axle, in a manner which will be readily understood without a more explicit descriptlon. The dust-guard D, sliding in its charnber in the box and following the vertical movements of the axle, around which it closely its, prevents sand or grit from workingv into the box and wearing away the axle and bushing.

Having thus described my invention, what I claim isl. In an axle-box, a body provided with a bushing, a hinged' lid closing the outer end thereof, a buffer on said lid provided'with a horizontal socket, and a detachable wearplate having an arm secured in said buffersocket, substantially as described.

IOO

In an axle-box, a body having a hinged lid, lin combination with a yoke hinged to the sides of said body and provided with a gravity-catch engaging the face of said lid, substantially as and for the purpose set forth.

3. In'an axle-box, the combination of a body, a hinged lid closing the onter end thereof, curved vertical llanges on said lid provided with yoke-ings, a yoke hinged to` said body and adapted to engage said lugs, and a gravity-Catch on said yoke, substantially as and for the purpose set forth.

.l. In an axle-box, the combination of a body, a hinged lid having an inwardly-projeetin g buffer, a detachable Weanplate on said buffer, outwardlyprojecting flanges at the vertical edges of said lid, a yoke hinged to said body and engaging lugs on said flanges, and a gravity-catch hinged to said yoke, snbstantially as and for the purpose set forth.

5. ln an axle-box, the body in Combination with the lid L, having the bnl'er E, formed integral therewith and provided with the socket g, the Wear-plate R, and key-pin. K, substantially as and for the purpose set forth.

G. The box B, provided. with the hingedld L, having the :flanges L' and lugs 7c, in eo1nbination with the yoke Y, having the hinged eateh C, arranged to operate substantially as and for the purpose set forth.

7. The box B, provided with the openingb, socket f, and bushing X, the lid L, having flanges li,thebnier E, provided with socket q, the weanpla-t-e R, having the arm llLLt-he keypin K, the yoke Y, and eateh C, constructed and arranged to operate substantially as and for the purpose set forth. i
